Brandon is very knowledgeable and a honest person . He made it easy for me to understand. How brakes work's.
To make a long story short Brandon is my mechanic from now on and I will be following up with his subjections to keep Miss Bessie running smoothly. Thanks Brandon

All about Brake Pad Replacement

Depending on your car’s brake system, it may use between 4 to 8 brake pads. When you step on the brake pedal, the master cylinder sends fluid under pressure to the brake calipers (which hold the brake pads). The caliper presses the brake pad against the brake rotor, causing friction that slows down the car. During normal usage of the brakes, brake pads wear out and become thinner. If the thickness of brake pads is less than 3mm, it is time to change the pads. Depending on where you drive (city driving tends to wear pads out quicker) brake pads usually last between 30,000 to 35,000 miles.
Some vehicles (e.g., BMWs) are equipped with a low-pad-warning system. In these vehicles, you will also need to replace the brake sensors as part of the brake pad service.

Regular maintenance and replacement of your brake pads is a very important safety measure. If you drive your vehicle with worn-down brake pads, braking distances increase, you risk damage to the brake rotors (which are more expensive than brake pads), and most importantly, you put yourself and others at risk. Brake repair should be completed if the brake pads are less than 3mm thick to ensure safe operation of your car.
